autojs 热更新dex 例子

转dex之前,先到 js 混淆网站里把 js中的所有的变量和方法名全部重命名。

将混淆后的js 再转 dex ,更加安全..

"ui";

var DexName = "aaa.dex";
var DexVersionName = "DexVersion.js";
//本地文件
var LocalDirPath = "/sdcard/xxx辅助/";
var LocalDexPath = LocalDirPath + DexName;
var LocalVersionFilePath = LocalDirPath + DexVersionName;

//网络文件
var RemoteHost = "http://自己的地址/";
var RemoteDexFilePath = RemoteHost + DexName;
var RemoteVersionFilePath = RemoteHost + DexVersionName;
